\[ \text{A} + \text{B} \rightarrow \text{AB} \]
Decomposition Reactions
A single compound breaks down into simpler substances:
\[ \text{AB} \rightarrow \text{A} + \text{B} \]
Single Replacement Reactions
An element replaces another in a compound:
\[ \text{A} + \text{BC} \rightarrow \text{AC} + \text{B} \]
Double Replacement Reactions
Exchange of ions between two compounds:
\[ \text{AB} + \text{CD} \rightarrow \text{AD} + \text{CB} \]
Combustion Reactions
Hydrocarbon reacts with oxygen producing carbon dioxide and water:
\[ \text{CxHy} + \text{O}_2 \rightarrow \text{CO}_2 + \text{H}_2\text{O} \]

Steps to Balance a Chemical Equation Using the Gizmo
Balancing chemical equations involves systematic steps, which the Gizmo helps users practice and master.
Step 1: Write the Unbalanced Equation
Begin with the correct formulas for reactants and products.
Step 2: Count Atoms of Each Element
Determine the number of atoms for each element on both sides to identify imbalances.
Step 3: Adjust Coefficients
Change coefficients to balance the atoms for each element, starting with the most complex molecule.
Step 4: Repeat for All Elements
Ensure all elements are balanced, adjusting coefficients as necessary.
Step 5: Confirm Conservation of Mass
Verify that the number of atoms for each element is equal on both sides.
Step 6: Simplify Coefficients
Reduce coefficients to the simplest whole numbers if possible.
